F(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a
f(x) = (5x+1) / x g(x) = x / (5x+1)
f(1) = 6, but g(6) = 6/31 ≠ 1
So, f(x) and g(x) are NOT inverse functions.
It is expected that a number greater than 4 will be rolled 300 times
The sample space of a die is:
S = {1,2,3,4,5,6}
The probability of obtaining a number greater than 4 is:


In 900 rolls, the expected number of number greater than 4 is:

This gives


Hence, it is expected that a number greater than 4 will be rolled 300 times
